Abstract
La présente invention concerne un dispositif (10) pour amortir les vibrations d'une structure (1) muni d'une masse principale (12) et d'une masse auxiliaire (20) montée sur un support (11) apte à être encastré dans ladite structure (1), ladite masse auxiliaire (20) comportant un organe fileté (21) agencé autour d'une vis de manœuvre (40) à l'intérieur d'un carter (30) fixé à ladite masse principale (20). Ce dispositif comporte un moyen de manœuvre (50) manuel en prise avec ladite vis de manœuvre (40) pour déplacer ladite masse auxiliaire (20) le long de ladite vis de manœuvre (40).The present invention relates to a device (10) for damping the vibrations of a structure (1) provided with a main mass (12) and an auxiliary mass (20) mounted on a support (11) suitable for being embedded in said structure (1), said auxiliary mass (20) comprising a threaded member (21) arranged around an operating screw (40) inside a housing (30) fixed to said main mass (20). This device comprises manual operating means (50) engaged with said operating screw (40) to move said auxiliary mass (20) along said operating screw (40).
